Scientists from the Institute of Psychiatry, Psychology and Neuroscience at King's College recruited 55 patients who had hepatitis C. The standard treatment for hepatitis C is the drug interferon-alpha which challenges the immune system in the same way as a powerful infection.

The team measured fatigue and immune markers before, during and after treatment, tracking which people developed the persistent CFS-like illness.

In the 18 patients who developed CFS-like symptoms the team found a much stronger immune response to the medication. Significantly these patients also had an overactive immune system before the treatment started.

"For the first time, we have shown that people who are prone to develop a CFS-like illness have an overactive immune system, both before and during a challenge to the immune system.

"Our findings suggest that people who have an exaggerated immune response to a trigger may be more at risk of developing CFS."

Senior researcher, Prof Carmine Pariante, added: "This is a light in the fog, a direction of travel. Although screening is a long way off, our results are the first step in identifying those at risk and catching the illness in its crucial early stages."

[Science study game] A useful app for chemistry classes. "Beaker by THIX"Science teachers need to prepare a lot for experiments with chemicals.You must do a lot to prevent accidents that may occur during class.At the end of the lesson, you will also have to work for the chemicals you use.
